न हि कश्िचत्क्षणमपि जातु तिष्ठत्यकर्मकृत्।
कार्यते ह्यवशः कर्म सर्वः प्रकृतिजैर्गुणैः।।3.5।।
3.5. For, no one can ever remain, even for a moment, as a non-performer of action; because everyone, being not master of himself, is forced to perform action by the Strands born of the Prakrti (Material cause)
3.4-5 Na karmanam etc Na hi etc. Knowledge, deserted by action, does not exist; and the action, combined with dexterity does not exist, [if it is] deserted by knowledge. Therefore knowledge and action constitute one and the same thing. Hence it has been delclared : Knowledge is not deserted by action and action is not deserted by knowledge. [Hence] a teacher who is well accomplished in knowledge and action, is the cutter of the fetters of the fettered. Therefore the action that is included within the knowledge cannot be avoided. For, the body, the organ of speech and the mind are, by nature, in a perpetual motion; and hence an individual, being simply under the control of other than himself, necessarily performs one action or the other. For, the body, the speech-organ and the mind are of the nature of throbing.
